Gemini API Context Circulation: Chain Google Search + Maps + Custom Functions in Single Calls with Cross-Turn Memory

Google Blog·medium signal

Google shipped context circulation for the Gemini 3 API (May 5): every tool call and response persists in model context so subsequent steps reason over prior results. Developers can now combine built-in tools (Search, Maps) with custom functions in one request. Unique tool call IDs enable parallel function calling disambiguation. Practical impact: eliminates manual orchestration between search-then-act steps, reducing latency and code complexity in agentic architectures.
